DUMP-CAR.

Application filed if 1111;: 8, 1912. Serial No. 702.5523.

To all whom it may concern:

Be it known that 1, Karen E. Hansen, citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Dump-Cars; and I do hereby declare the following to be afull, clear, and exact descriptionthereof.

My invention relates to dump-cars of the tilting-body type.

The object of my invention is to provide a simple and eflicient form of mechanism for tilting the body of the car by a direct posi tive vertical push from a vertically actuated piston located on the underframe.

Referring to the accompanying drawings Figure 1. is a longitudinal elevation of a car embodying my invention; Fig. 2 is a cross section on line 2--2 Fig. 1, one of the arms being removed to make the illustration clear; 3 is a similar view showing the car in dumping position; and Fig. 4 is a view looking in the direction of the arrow at Fig. 3, the car body being broken away, and the lugs 011 the car body shown in section, and Fig. 5 is an enlarged perspective view of the push member.

In Fig. 1 I have illustrated a dump-car of the tilting-body type, in which the car is pivotally mounted along a center line, and as my invention does not relate to the details of the construction of the underframe and other parts it will not be necessary to refer to same in. detail. The dumping-body 2 is provided With the brackets 3 which are pivotally mounted on the standards at of the under'trame by means of the pivotal pins At or about the mid-point of the car are the cylinders 6 and 7 which are supported in any suitable manner on the underframe. Air or other motive fluid may be cylinders from any suitable source. The piston-rods 8 are connected to suitable pistons within the cylinders and the upper ends of said piston rods carry the cross-heads 9. These cross heads have jecting out therefrom. Brackets il are secured to the bottom of the car at each side of the center line of said car and said brackets are provided with the lugs 12. A clevismember 13 is connected to the bracket 10 by means of a pin 14 and clevis-member is adapted to swing on said bracket. The clevis member 13 is provided with the cars 15 to which the arms 16- are supplied to said the trunnions 10 proin this manner said specification of Letters Patent.

pivoted by pins 17. The mounting of these arms in this manner holds the pin i l in position and prevents its dislodgment as clearly indicated in Fig. 4t. The armslti in the normal position of the car hang in a substantially vertical position, and when in this position the faces 18 abut. The lower ends of the arms 16 are provided with the seats 19 with the curved upper portion 20 to receive the trunnions of the cross-heads 9. The arms are further recessed as at 21 to receive the cross-head 9 when the cross-head is moved up to engage said arms. The clevis-member l3 and the arms 16 form what may be broadly termed a push-member The lower ends of the arms 16 are beveled as at 22 and below said arms and in the path of same, on the descent of said arms, are the inclined planes 23 located adjacent to the cylinder heads. These inclined planes act to deiiect or force the arms 16 apart, as clearly indicated in Fig. 4, when the car is dumped in the position indicated in Fig. 3, as more fully hereinafter set forth.-

The clevis-member 13 is provided with the stop24 and said stop acts to regulate the movement-of the push-member when the car is1 dumped, as indicated in Fig. 3. In this position of dumping the stop 24 comes in contact with the bottom of the car or other fixed abutment, and prevents the push-member swinging into a vertical position which it would naturally assume, the purpose of this being to hold the push-member in a position approximately at right angles to the bottom of the car when elevated, so that there will tical thrust of the piston, and the pushmember will be held from swinging over and causing a side thrust on the piston-rod 8.

In the dumping operation one of the chains 25 having been released, motive fluid is admitted to the cylinder 7 at one side of the car and the piston-rod 8, together with the cross-head 9, are moved upward. The crosshead moves into engagement with the recesses 21 in the lower ends of the arms 16 and the trunnions 10 lit in the bearings 20. As the upward push of the piston is in a vertical line there is no tendency of the arms 16 to separate, and as the stop 24 on the clevis member engages the'b'ottom of the car the arms 16 are held from swinging into a vertical position, and consequently the directvertical push of the piston rod dumps the piston 8 is be a direct vercross head as indicated in 3.

ter

' arms are and gradually spreading said arms until cal push to the push member adapted to engage p car. After the car has moved sufficiently the puslrmember will separate from the This will not occur, however, until a the piston has done its work] The stop 2d prevents the swinging of the push-member and consequently obviates the side thrust on the piston rod during the upward movement of same. As the opposite side of the car is lowered the arms [L6 on that side come in contact with the inclined planes 23 and said deflected; or separated, the bevel portions 22 traveling down the inclines 23 they assume the position indicated in Fig. 4t. In this manner therefore provision is made for moving said arms out of the way so as not to interfere with the cylinder-head 6. When the car-body is brought back to normal position after the dumping operation, the. arms 16 will resume their normal positions at opposite sides of the car and said car is then in position to be dumped from either side as may be desired.

By my invention 1 provide means for dumping the car-body by the use of a fluid operated piston with a piston-rod moving in a vertical line and applying a direct vertimember while at the same time .the push arms at the opposite side are deflected so that there is no interference with the downward movement of the. car-body on that side. a

What I claim is:

'1. Ina dump-car, the combination of a tilting oar-body, a vertically actuated piston rod, 2. pivotally mounted push-member-in the path of said piston-rod, and means for maintaining said push-member at substantially right angles to the bottom of said car in the tiltin position of the car-body.

v 2. In a ump-car, the combination of a tilting car-body, a vertically actuated pistonr0d, a pivotally mounted push-member car ried by said car-bodyin the path of said pistolrrod, and a stop carried by said pushsaid car-body when said piston rod is elevated.

3. In a dump-car, the combination of a l tilting car-body, a vertically actuated pistoni a rod, a puslrmember carried by the car bodv rod, a push-member carried by said car-body comprising swinging, arms in the path of said piston-rod, and means'tor deflecting said arms on the side the car is dumped.

A. In a dump-car, the combination of a tilting car-body, a vertically actuated piston rod, a push-member carried, by said can body comprising a pair of swinging arms in the path of said piston-rod, and means inthe path of said arms to deflect same.

5. In a dump-car, tilting car-body, a vertically actuated pistonrod, a push-member carried by said carbod comprising a pair of swinging arms, and inclined planes in the path of movement of said arms to deflect same.

6. in a dump-car, the combination of a tilting car-bot y, a vertically actuated pistonrod, a push member carried by said carbody comprising swinging arms, said arms having beveled portions at the lower ends, and inclined planes in the path of said arms to deflect same.

7. in a dump-car, the combination of a tilting car-body, a vertically actuated pistoncomprising swinging arms, and a crosshead on said piston-rod adapted to engage said arms.

8. in dumpcar, the combination of a tilting car-body a. vertically actuated pistonrod, a push-member comprising a pair of swinging arms having recesses at the lower ends thereof, and a cross-head on said piston-rod adapted to engage said recesses.

9. In a dump-car, the combination of a tilting car-body, a vertically actuatedpistonrod, a cross-head on said piston-rod, trunnions on said cross-head, a push-member comprising a pair of swinging arms having recesses at the lower end to receive said cross-head, and seats to recelve said trim-- nions.
